I'm administering a server which is managed by plesk. Also there are additional programs installed, like ldap for example. And there has been a ton of changes to configurations around apache, like several changes to python or ruby that power different websites/webapps. For backups there is a server, reachable via ftp, same disk size as the server.
The Plesk backup is nice and backs up stuff that is managed in plesk to the ftp-server and can restore it from there. The problem is all the additional stuff around. Like config files for ldap, apache, additional installed packages required for several configurations. Those files are lost after the server is dependent if all left is the backup. This would require days of work to setup everything again.
Question is: Is there a good strategy to backup that other parts, too? Are there any best practices available? Which tools are beeing used? Like run my own backup and restore scripts which are hooked into the plesk backup? If not everything of what I mentioned is backuppable, what of them is and which way you would recommend based on your experience?
Thank you very much - gossi
